This invention relates toan improved kitchen utensil for shredding orgrating foods. object of the invention is the provision of shredder andgrater which is divided into several compartments for receiving the foodto be acted on so' that when the cutting device is operated thedifferent kinds of food will be sheared'ofi and deposited in separatepiles in a receiving compartment. Another object of the invention isthe-provision of a'device for shearing ofi particles.:- or l,'strips ofone or more vegetables which are adapted to be employed in salads orwhich may be" cooked, the construction being such that the particles ofthe vegetables when two or more are usedfor acted on will be depositedin individual piles so that said piles may be removed separately from areceiving chamber and be mixed together in the proper proportions asdesired, a partition being provided in a shearing chamber formaintaining the vegetables out of contact with each other during theshearing operation. r *A further object of the invention is theprovision of a device for shearing off particles from two or morevegetables simultaneously in such manner that danger of abrasions to thehands of the operator is eliminated while reducing the labor in thepreparation of certain kinds of food, said device including a rotaryshredder or grater dividing a housing into a shearing compartment and areceiving compartment, a partition dividing the shearing compartmentinto two or more sections or chambers to contain the foods to be actedon, the receiving compartment being beneath the shredderor grater sothat the sheared vegetable particles will fall into individual pilesandmay be removed separately, theshredder or.

cbnstructed in accordance with tl' 'e principles 'of' my invention.

Figure 6 is a view in perspective of a shredder which may replace thegrater shown in Figure 5.

Figure 7 is a vertical section of a presser taken along the line 1-1 ofFigure 8, and

Figure 8 is a bottom plan view of the presser shown in Figure 7.

Referring more particularly to Figures 1 to 5 inclusive, I0 designates acylindrical housing which may be made of metal or of plastic materials.Said housing has a circular bottom II and an open top l2 and is dividedby a grater disk l3 into an upper shearing compartment l4 and a lowerreceiving compartment [5. The upper compartment has a slightly greaterdiameter than the lower compartment due to the fact that the walls ofthe upper compartment are flared. The upper wall is provided atdiametrically opposite points with thickened portions I6 to reinforcethe wall where vertical slots I! are formed for a purpose which will bedescribed presently.

A flange 20 is formed on the inner wall of the receiving compartment l5just below the grater disk [3, affording a bearing support for the diskwhen heavy pressure is exerted on food placed on the disk. Adiametrically disposed bar 2| is integrally formed with the flange andhas a central opening 22 which receives the upper end of a shaft 23which provides a partial bearing for said shaft. A metal collarcompleting the bearing for the upper end of the shaft 23 is embedded ina pocket in the bar 2| and is secured to the bar in any approved manner.

A centrally disposed boss 25 formed on the bottom I I of the lowercompartment !5 has an opening alining with an opening in the bottom toreceive-a reduced portion 26 at the lower end of the shaft 23. A collar21 mounted on the reduced end of the shaft rests on the upper surface ofthe bottom I l of the housing and not only retains the shaft in thehousing when the grater I3 is removed but provides a bearing for thereduced end of the shaft. A shou der 28 formed by the re-" duction ofthe lower end of the shaft supports the stamped from a sheet of metal toprovide raised cutters 35 (Fig. 5), with corresponding openings 36through which the pieces of food pass after they have been chipped oilthe mass of food placed in the shearing compartment 14. A hollow boss 31is formed centrally on the disk l3 and is internally threaded to receivethe reduced threaded upper end 38 of the shaft 23 (Figure 4) A post 39rises axially from the boss 31 and terminates slightly below ahorizontal plane passing through the upper open end of the housing l andis provided at its upper free end with an internally threaded pocket 40.

A partition 45 which divides the upper compartment it into two chambers46 and 4'! hasa centrally disposed sleeve 48 received by the post 39. Ascrew 49 threaded into the 'pockethas --a head bearing on the upperend-ofthe sleeve .48 for retaining said sleeve on the post. The freeends of the partition are received by the diametrically disposed slotsl! at the inner face of the wallof theupper compartment forretainingzsaid partition against rotation. Thepartitfonis :provided withno'tches'5l atits opposite ends sothat the lower edge will fall belowthe lowerends of theslots I? and will be in close association wlith theater l3.

.-A substantially rectangul-ar opening 52 is formed in the wallwof thelower-compartmentfl with the lower edge of said opening flush-with theinner surface of the bottom .H with: housing so that the lowercompartmentmay be cleaned thoroughly. Aspout 5'3 has'a bottom portion 54andside walls 55. The inner end of the walls project through the opening52 into the compartment i5 while the-inner end of'the bottom 54 extendsbelow the bottom H of the housing. The upperinner end of each sidewall55 is provided. with a notch '56 adapted -"to receive the sidewall ofthe housing at the upper edge ofthe opening 52 in the compartmentl5. Bythis construction the spout may be removed or replaced readily whendesired.

A U-shaped clip S'Jhas itsbridg'ingportionifi'l secured by bolts 62 tothe outer wall ofthe compartment 1 i. The flanges 63 of the .clip haveoutturned ears ii l'which are adaptedto be received by complementaryguides: formed on a well-known type of wall bracket (not shown).The'flanges B3 are inclined toward each other for retaining theclip inthe bracket.

InFigure 6 is shown a shredder'which is'substantially identical inconstruction except for'the shearin e ements. Inthis case the diskl.3--ta is punched to provide elongated'raised cutting blades] 61, Sincetheother elements ar -identical to similar elements shown inFigm'ei5gthesame reference numerals will be applied.

Ether-the grater 13 or theshredderrl3-a may lie-employed and the onemaybe substituted for the other. As previously indicated, the graterand" shredder are interchangeable and when 'this isdesired, it isony'necessary to applypressure upon tescrew 50 which has left handthreads and then rotate the handle in ra' reverse dipresser consists ofa circular disk H from which depend a pair of semi-cylindrical blocks 12Whose inner flat faces are spaced from each other to provide a passage13 to receive the partition 45. Each block has a semi-circular groove toform a central passage 14 to receive the sleeve 48 on the centralportion of the partition. A handle 15 is secured to the top of the diskfor operating the presser.

.If one kind of food is .toibegrated, such as carrots, said food isplaced in both chambers 46 and 41 and the crank is operated while theplunger "lfl is pressed upon the food. On the other hand, if two kindsof food are to be grated, one such food is placed in the chamber 46,while the other food is deposited in the chamber 41. Thus it .will beseen that carrots may be placed in one chamber while cabbage may beselected for the other chamber. In this type of operation, the gratedcarrots will fall into the compartment l5 and will form a pile, and thecabbage .williall into a separate pile from the chamber above. Thegrated products are removed through the spout 53.

In a like manner,.the member I ii-a is employed forshredding lettuce,cabbage or various foods. The shredder l-3-a may be readily substitutedfor vthegrater as has been explained,.supra and vice versa.

The plunger maintains the food in operative engagement with the cutterson the-grater 13 01 the shredder l3a. Said plungeris limitedin itsdownward .movement when theunder .face. of the disk H oisaid plungerreaches the upper-edge of the partition 45, so that the bottom .face'ofthe plunger will not comeinto contact with the grater or shredder.

The partition V I 5 includes the centrally disposed sleeve 48 which isloosely mounted on the .post 39.and a plurality of wings .45-cradiatingfrom the sleevein .a verticalplane. It will=be appreciated that whiletwo .wings are shown, .a-greater number of Wings maybe employed fordividing the uppercompartmentinto three. or more chambers. This .willbe.particularly effective when the housing oftheutensil. hasalargediameter and is employed .in the kitchens of restaurants and hotels.
